Which logic gate is represented by the following combination of logic gates? Which logic gate is represented by the following combination of logic gates?

Options

  1. AOR
  2. BNOR
  3. CAND
  4. DNAND

Correct answer

C. AND

Step-by-step solution

Which logic gate is represented by the following combination of logic gates? Output of gate-1, Y1=AˉY_1=\bar{A} Output of gate-2, Y2=BˉY_2=\bar{B} Output of gate-3, Y=Y1+Y2‾=Aˉ+Bˉ‾=Aˉ‾Bˉ‾=AB\begin{aligned} Y=\overline{Y_1+Y_2} & =\overline{\bar{A}+\bar{B}} \\ & =\overline{\bar{A}} \overline{\bar{B}} \\ & =A B \end{aligned} which is the output of AND gate.
